Palio Blitz is about 1/3 the price of Tenergy and about 1/2 the price of most other top shelf rubbers. As such it is reasonable value. If however you can play well with a cheaper rubber such as LKT rapid speed then that is great. Go for it!
It's not that cheap it's almost online with the price of other rubbers, aside from Tenergy
I'll try the 42 version IF I have the occasion to do so without buying it first, maybe the 47.5 version just doesn't suit my play but what I'm basically saying is that in real world it got to be a great difference in quality between a $28 product and a $12 product to let you pick the first, especially if you have to pick at least two, just like car tyres, so far I'm not finding big differences between these two products :
Foam is hard on both of them, top rubber is a quality one, and still I play better with the cheaper one, I haven't been paid by LKT to do their publicity, I have many other brands at home at home, (yasaka, stiga, tibhar, donic, reactor, joola) I had stopped TT for 8 years, and now I'm back at 35 years
Still decent level (I have around 1000 points in the french ranking level) but I now think that a word of wisdom for players who just wants to enjoy playing table tennis is to stop trying to decipher equipment reviews to pick the best combination possible and to stick with the first combination they are comfortable with, as they are likely not to find MUCH better, unless they spend a lot of money trying almost every rubber out there, unless off course you have a very high level and the slightest detail is of importance for you, but then again if you're in that case I guess that you'll be able to try what you want for free
