I'm taking a total shot in the dark here. Your blade doesn't seem to be the problem if you lack control.
If your main problem is shots going too long on passive blocks or soft loops, maybe consider switching to harder rubbers for better control. Based on how much you play and work out, I think you are more than strong enough to generate good spin and speed with hard rubbers. Soft rubbers allows you to generate better spin and bounce with low power input, but give you less return on high power inputs. You are using M3, the softest in the Bluefire series, on FH. This might be the reason why your kill shots feel slow, yet you struggle to keep balls on the table with some of the soft or passive shots. Switching to M1 might solve this problem.
If your BH is weak, use a softer rubber than EL-P (maybe FX-P). Hard rubbers only come alive with more power. With low power input, they feel dead compared to soft rubbers. Like I said, the whole point of softer rubber is to allow you to generate good spin and speed with small power input. You might find it a lot easier to lift backspin and loop kill with BH once you switch to a softer rubber.
Softer rubber doesn't necessarily equate better control, and hard rubber doesn't necessarily mean faster shots. It all depends on how much power you put in.
