OK so I found my dime bag of tips and have tried the UE tips and found they worked very well so I like the shallower Meelec single flange which is very soft and conforms to my ears well. But the UE tip is a bit sturdier and slightly deeper giving it a bit of different sound. I think I will have to try the Sensorcom tip as well. In any case my only quibble with the SM3 (recessed treble) is pretty much removed with these tips. I know there are brighter or more treble present IEM's on the market (DBA2 for one) that are not harsh, but with this tip combination on the SM3 I think these are as much treble as I can handle.
I have one of those custom ear mold kits coming in from the earplug store though (schwallman's posts have given me the confidence to try doing this on my own). So after I try doing that if I really like how they feel I may still go custom (tip or shell, still not sure which). If I am not as happy or comfortable with their feel I think I will just stick with these wide mouth tips.
BTW when you guys are using the comply core as a spacer, do you seal it on the tip somehow or just shove it in? I have been just shoving it in but wonder how much sound is getting leaked around the core and the tip.
