You can handle end issues with slotting and IO's...
Musculature all the way baby...
The hard things I can do--- The impossible just take a little bit longer.
If numbers are so much more important than a teammate who is fun to play with, forget about the game altogether and go play with a calculator instead. -Claws and Effect-
You won't be having inf issues for long if you are doing Incarnate trials. It shouldn't take too many of those to fully IO out your character (as long as you don't feel you have to have purples or PvP IOs) so I'd go Musculature. Blasters rarely have real endurance troubles unless they don't slot their attacks for end reduction or they run a ton of toggles... since you aren't running Leadership toggles or Tough and Weave I can't imagine you still having trouble once you are well slotted. You might also look into slotting either a -KB IO or four Kinetic Crash (I like using the whole set in Power Thrust for the -KB and recharge) to deal with most KB and not running Acrobatics unless you are up against holds or high mag KB... that would pretty much solve your endurance issues even on SOs.
You can run two or three sets of Kinetic Crash on an Energy/Energy without too much trouble... it's a cheap way to get recharge and KB protection. I wouldn't put it in a major attack since it only has around 69% damage enhancement, but Power Thrust and Power Push are both perfect places for it. For that matter, with Musculature you can still get 112% damage slotting from a level 50 Kinetic Crash set and ED capping only pushes that up to 130% or so... so you may want to slot Kinetic Crash in Energy Torrent and Explosive Blast too for more recharge than Positron's and a much lower price. Four Kinetic Crash sets would pretty much mean you never had to worry about KB aside from the handful of stupidly high mag attacks that knock back everyone who isn't immune to it as well as giving you 30% recharge, and you can drop cheap Thunderstrike sets in your single target blasts for ranged defense and accuracy.

So I finally got my old En/EM/Force onto the incarnate ladder, and I found myself unable to choose:
1) Musculature for more damage
2) Cardiac for more end.
The situation is a partly (due to inf) IO'd character, usually running CJ/Acro/TI as toggles, doing a mix of all content (solo, team and trials.) Now solo, I'd been having end issues occasionally, but this does raise a question.
Does the extra damage from Musculature balance out against the extra endred from Cardiac, in a more DPA/DPEnd kind of way? Also, must admit, liking the idea of the extra 20% range, but not sure how useful it is with boost range nearly perma. I have no recharge issues either, so it comes down to which will make my life simpler.
Thoughts from people who've been down this road?
Do not go gentle into that good night.
Rage, rage against the dying of the light.
