I love the RM2 for my style of vaping. I do 3 to 5 second long pulls with the air intake hole opened up a bit. Mouth to lung and I always get great flavor. The only real downside for me is that I think the posts rotate and can snap at the threads too easily. Now, the o little 16 solves that problem. I think it will last a lot longer than my many RM2s.
I've tried a handful of other atties, many in the 22mm arena, but the 14s and 16s just work better for me. Oh, it's always either a 28ga single parallel coil or 28ga twisted single coil. Comes in about .38 either way.
1.3mm if I remember correctlyCan anyone off the cuff remember the standard air hole size in the RM2?

Today I tried Stainless Steel wire for the first time.
Did a simple 8 wraps around 1.6mm for the RM2. Came out at 0.57 ohms. (About half the resistance of Kanthal) I used 28g SS 317 from UD for this coil.

I did compress the coils a bit afterward The wraps looked a bit spaced in the photo. Lol.
First impression is wow - it's great. Fires with lots of vigour.
The problem with Kanthal for a simple 7 or 8 wrap single is that the resistance (around 1 to 1.2 ohms) is too high and the vape for me is a bit too mild.
I don't like 26g because of the afterburner and ramp time. I also like the thinner wire for the crisper vape it produces.
So I was resorting to 29g para coils using Kanthal. Enough wraps and low enough resistance.
So far this simple single SS coil is doing very nicely. Very similar vape experience to my paracoil with 10 total wraps.
I was a bit worried about pushing 30W in only 8 wraps given the small diameter, but hey, its working great!
I have Hardwicks DDD in there so I can compare with the same juice on the Kanthal paracoil in REO black. And the SS coil is doing very nicely. Perhaps a slightly unfair comparison because the Kanthal paracoil is a lot older and this is a new coil.
This is what I love about Vaping. Always surprises around every corner! Lots more experimentation to come.
PS - thanks to all the SS users for nudging me and to @Sprint today for you comments about the para SS coils which made me go try this simpler one out.
@Silver , I did a paracoil with 26ga Ni80 wire yesterday 8 wraps on my RM2 2mm. Came out 0.30 ohm. The heating"Ramp" time of the Ni80 wire is quick in comparison to Kanthal or SS and the flavor is excellent. I want to try Ni80 28g wire. My atty is on one of the Reo Mini's. Nowadays I use only Ni80 wire on all of my builds.Today I tried Stainless Steel wire for the first time.

Looks cool, I have yet to try SS @Silver, the "afterburn" effect is caused by the cotton being burn't and separating inside the coil. Used to happen to me all the time with small diameter coils. You should try using a 2.5mm coil with a Scottish wick, with a 2mm airhole. It transformed the RM2 into a winner for me.

Thanks @Petrus
How does the resistance of Ni80 compare with similar
Lower ohms definitely. Faster ramp up time. Higher wattage vape on a mech like a Reo. I genuine like this wire.
Hmmm... I'm gonna have to give this ss wire a go. I just know it.
I like Ni80 for certain applications, but I've always been going back to the kanthal wherever it worked well enough. I, too, dislike the ramp times for larger gauge kanthal and working with 28g ss sounds a treat for my 14mm flavour-first atties. Love to try a build in, say, a graal or a viper.
Dynamite comes in small packages !
Ok I was so happy with the SS coil in REO Silver I decided to do a similar thing for REO Mini.
She has had a 0.9 ohm Kanthal single in her for a while and she is dedicated to my Choc Mint Coffee blend.
Coiled a 9 wrap SS. Came out at 0.65 ohms. Was a bit worried about the 6.4 amp load on the little Efest 18490 red but I hoped they would handle. Was actually aiming for about 0.7 or 0.75 ohms.
Anyway this is very good. It's the strongest I have had REO mini fire in her life and she is rocking big time.
I know this flavour intimately and it's very good on the SS.
Stealth machine of note.
Loving it.

Just did some checking and discovered I am ok with those little 18490 Red Efest 1100mah nipple tops.
They can handle 8.8A.
Am firing at about 6.5 Amps at full charge - so I am okay.
I wont go any lower in resistance though - and my batts are ageing.

Can the airflow hole be made bigger on this atomiser ? If yes, what is the suggested size ? Can you add an additional airflow hole ?
Thanks, agree, flavour is great, but I am battling with it's tight airflow. Can I assume the 1.6mm is the standard hole? I think maybe even just one more hole the same size will give just enough for my pulls.Yes and Yes if you want to... the airholes range from the standard size to 3mm for some people who want massive airflow but I find the bigger the airflow the less concentrated the flavour becomes. Personally I like it at 1,6mm... but it's personal preference.
