If you're striking prior to leaving the 8-10, your entry angle normally isn't that bad. However, if you left an 8-10, you threw a bad shot. I've seen people with high rev rates leave them a few times just because they threw it too fast and the ball skated through the puddle in the middle of the house shot, for example. A little extra deflection with a small entry angle on a light hit is all it takes, just like leaving the 7-10 off a light pocket hit.
Last year, I threw the ball like absolute dogsh*t once after getting the front 9 and left an 8-10 on the first ball of the 10th frame. Cost me the chance at a 300, cost me all of the jackpots that game (all I had to do was mark and I would have swept the pots that game), and I'm pretty sure it cost my team the game as well. I can count the number of times I've left the 8-10 since then on one hand. So yes, I too hate the 8-10.
