Concur with much of what has already been posted. I've had layoffs from the sport across two different periods of time. The first was most of the 90's (left as the first resin was coming into the market place), returning circa 2000, and bought into the hype that new equipment was needed...it really was not, at least for what we now recognize as a THS.
The current 'away' period has basically been the past four years. My last league was in 2005. You could count on one hand and have four fingers and a thumb left the number of games I have bowled in the past two years until last Friday. Now you still have two fingers and a thumb left.
My office had decided that they wanted a 'bowling party' as the xmas party instead of the usual catering in the office. I dug out a selection of equipment that would work just about anywhere. While the office is in the middle of nowhere, it is nonetheless a synthetic house that runs a number of leagues. We were on leftovers from the night before. Quite frankly, I am scared to think how ugly it might have been with anything more powerful than a SonicX and Pearl Assault. I also had a look down and in with the Clear Grenade (plastic). In other words...the THS is still the THS is still the THS.
Use the old stuff...you should be fine. You might not cover as many boards, but there is more to bowling than the number of boards being covered...
