Upgrade to couponpress responisve theme good or bad idea?

Mark,
I am not sure what happens to some of my posts so I hope this isnt redundant however, I need to know if by upgrading to the responsive theme would be ok for me since I was having so many issues after the 3.6 update etc. I fixed a lot of the problems but there are still some annoying leftovers and I would just rather be done with the repairs and get to the fun part again. After all the research I think I would prefer the new responsive coupon theme anyhow. So will it work and rid my site of its troubles, do i get to replace the old or is it an add on and if so, am I just asking for trouble and applying a band-aid that wont stick or fix it at all? What can you suggest please?
