Matt/PA, If the Patriot lives up to its billing, it is going to be one awesome piece of equipment!
I got to thinking and I just realized I have never shot the Ultra Max with the Harmonic Dampners so I can't speak with authority on how it shoots now but I did shoot the old style and I never considered them that quiet or shock free especially compared to the longer riser series bows in the Mathew's lineup.
I don't recall now which bows of the Bow Tech line I shot last year (one of the problems with getting older

), I know it wasn't the BK. The ones I shot had the Sand Trap technology but again I felt noticeably more hand shock than I thought I would (that is one of the down falls of falling for all the "hype" that goes on in our industry).
Your statement on making the speed equal in testing the bows sounds good, but seems quite the reverse of what I would do. As you know by the bows design it embodies certain qualities like speed, vibration, noise, etc.. So I don't think by turning the bow down until you match speeds to compare the feel, would be my preferred method. I want to feel the bow at the poundage and draw length I am going to shoot it at. After all, it is the increased performance that we're after, as long as that performance falls within the acceptable comfort or "feel" range. It's no big deal, that is just the way I would make a comparison for me personally.
Yes I anxiously await the day I can shoot the Patriot and I will certainly give the Pro 38 a "go round" too. I am kind of partial to the longer ATA bow myself.
