Bias Alert - I am currently long AVLE
This is still my wife and my favorite game. We have had it for about 8 months and still push start all the time. I admit, the rattly ball launches have proven difficult to resolve and is getting old but all other issues have been resolved months ago and has not required continuous tweaking. Fix it and forget it, for the most part.
It has made my wife and I better players. If you can consistently hit all the AV shots, those skills transfer to other pins quickly. No better feeling than hitting BW 4 or 5 times in a row! Now if I could just do that for the IM shot!
