Today is your luck day! 
I have a high level fire/fire AND a high level SS/Elec!
Fire/Fire
-Pros: Good self heal, avarage resistance numbers, you'll enjoy all the effects from Fiery Embrace, nice damage aura, AoE attacks, fire is not so resisted, DoT, offensive set
-Cons: No side-effect from the attacks besides DoT, no God mode, you need to die in order to use the tier 9 power, you need to kill fast or you wont last (offensive set), you need to take SJ as your travel power (along with CJ and Acrobatics), no fear/confuse/end drain/Psi/Toxic protection.
Well, as you can see from my signature, I liked playing with him and I can PvP, although I'm not the most feared toon on RV hehe. Keep in mind that you'll need to be fast (Hasten is a good option) and you have no damage mitigation (I took the Presence Pool). but I gurantee it's a fun set.
SS/Elec:
-Pros: Good Mez protection, TP protection, end drain protection, good endurance management, slow resistance, damage mitigation (Knockback), KO Blow (Hold), +20% recharge, God mode, Rage, Psi resistance
-Cons: No self heal, smashing damage is highly resisted, you'll lose some mez protection if you jump or fly, no fear/confuse/toxic protection
You stand longer with this build as you'll be able to mitigate some damage. Aid Self is mandatory and you'll need to learn how to use Rage in order to deal good damage in mobs with high smashing resistance.
I can tell you that after leveling my SS/Elec a bit, I forgot about my Fire/Fire. I still PvP a bit with him, but Promethean is much more fun!
Ma suggestion: SS/Elec. You wont be disappointed.
SS/ is great in pve, really. knockbacks, footstomp, emergency-hand clap, RAGE (<- !!), good damage. the smashing-only damage aint too bad in pve, unless you want to pvp alot i would say go SS/.
for pvp you probably want more burst damage (EM/) and secondary effects like disorient (EM/) and lesser-resisted damage types (EM/).
DM/ seems to be good in pvp too (some ppl love it), personnally i dont like DM/, shadow maul annoys the heck out of me so i dont play my dark/dark (40) anymore.

no toxic protection???? erm think someone needs to re read the descript on healing flames again....
just most tend to use it as a self heal/hp buff and forget about the other effect 
its the pixie dwarf :P

OK... 15% Toxic Res, I know. But nobody slots HF for resistance. No thing compared to a 40% Psi resistance from Static Shield.
SS/Elec with aid self and tough is awesome
