hit a plateau.. help?

[tattedlegend]

Just as a followup to tattedlegend's earlier post. I noticed he uses an ascending pyramid weight protocol (135, 165, 185, 205lbs). Personally i use a descending pyramid (250x5, 225x8, 200x10, 180x12, etc). I always felt while building size and strength, start with the heaviest sets first to activate the fast-twitch fibers first and then the slow-twitch fibers with the lighter weights. They say that the average lifter has about a 50/50 ratio slow to fast twitch. From your experiences which is better for building muscle and strength simultaneously, ascending or descending pyramids?

I actually just recently transitioned over to a scheme like this. For example my last time benching I did warm up of 135 for like 10 reps, warm up of 185 for 5, then went immediately into sets of 205 by 8 reps, then 6 reps, then descended back to 185, then 155 till exhaust. I understand your logic behind it as well. Hard to say if I notice BETTER gains either way, versus just switching it up to keep the body guessing.
