I tend to agree with your statement about the house shot. When I started bowling again this spring, I was having trouble converting my spares on a house shot. I wasn't, however, using the 3-6-9 system... using the Tennis system learned over the years prior to reactive. I ended up pulling out my circa late 80's, early 90's urethane ball for spares. I'm gonna give the 3-6-9 a whirl and see. I can change despite being an old fogey!
