I also took the Hammer Demo Challenge 4/10 -- in Hurst, TX-- Same problem as you -- I was in a house w/synthetic lanes that I had never bowled in -- could go way outside and play the 4-board straight up and just walk that ball into the pocket....I bowl one night a week on thirty year old wood lanes -- the shot there is inside-out --- between 2-3rd arrows to start and closer to 3-4th as the shot breaks down, depending on how far in you like to go...I brought my Big Blue and Hammer Vicious with me to throw a couple of times as "benchmark" shots-- the drillings on the test balls are "generic" so you get to see the true action of the ball.  I went there mostly to test the BBP-- I found that it did go a lot longer for me than Big Blue -- then made an arc and hit H-A-R-D--actually suprised me now hard it hit-- Looking for something I can stay on the right side of the lane when they start to break down -- but I still can't say how the BBP will handle carry-down.  I would think the rep gave you good advice  provided its short oil.  I also threw the Vicious Strike -- has a bigger move than my Vicious, but Don't see as I need it right now based on where I'm bowling.  Most impressed with the Vicious Attack -- to borrow a phrase, kind of like my Vicious on steroids -- big hit, but I can see me being able to swing the Attack, whereas I use the Vicious more straight up -- hope this input helps you somewhat.  Feel free to message me if you want any more details.
