Much is going to depend on your interpretation of what exactly a "lightning fast action" is. I have the 11' Acolyte Ultra (and several other Acolyte float rods). I feel that the actions are very similar across all the different length Ultras and Pluses. I have a feeling that if you didn't like a 13/14/15' Acolyte Ultra, then you probably won't like the 11' Acolyte Ultra.
I know others will disagree, but I feel that the Acolytes are a bit of a half way house action for those that prefer a few rods to do everything. They are inbetween my idea of a fast actioned trotting rod and a more through actioned waggler rod. If your point of reference is the 11' Drennan Matchpro Ultralight, then the 11' Acolyte Ultra is a faster action but similar power.
Until last year, I had an 11' Matchpro Ultralight. It ended up being sold because I had other options. I have a light canal type waggler rod that I prefer on stillwaters and the Acolyte was used on becks/small rivers. However, I recently shortened a 13' spliced tip rod for the becks/small rivers which has left the Acolyte close to redundant.
