I thought the BP felt more plush than the UP, subtle but there. Maybe it's how/where they flex, don't know not a scientist.Late to the party, but how does these compare to the Blade Pros? Currently maining the BP 16x19 at 338SW.
BP16M has a higher launch angle, more power, less precise.
I could not get my string and tension combo right with the BP either.
The launch and power of the BP 16x19 were not for me so I switched off. Always thought the 18M version might've been a good middle ground, but never picked one up.
UP16M pretty much does everything I want, no complaints.
