I'm not sure what the answer is... I've owned both T2 and HS2. I enjoyed both the same. HS2, I felt, just didn't have enough for me to make it a long term keeper. Definitely enjoyed it, just not a homerun. Shots, for me, just got a little repetitive. T2 is fun also... not sure how well it would hold up as a 1 pin... but, the beauty is you can always trade or sell!
If you go JY... you'll be spending more. If that's the case get two machines rather than one. But, if you get two... I wouldn't get two SR pins. Mix up the designer some. So, I guess my vote would be BR and HS2 or BR and T2.
