solid sponges boost better as they expand so much and stretch the top sheet, saying that there is hardly anything sold with solid sponge anymore so you should take the step to get rid of those awful snipe 3 rubbers. Nice euro wannabe's but look in the budget basket and for not much more you can pick excellent alternatives from Joola/Donic/Andro/Tibhar...
Tensor is just porous sponge that boosting doesn't affect it as much, they are factory boosted to make them play more lively and have great catapult. The new 3rd and 4th generation Tensors are coming with swiss cheese sponges and they need to be harder like 47-50deg otherwise they play like mush hence why some people are not too keen on 45 ESN rubbers and mention they feel more like 42deg. This is why when you touch your Focus Snipe 3 and then Tenergy 64 you realize there isn't much difference on the softness. A reason why people still like Tenergy due to the smaller pores however MX-P and some other 47deg rubbers have brought back the smaller pores compared to the big swiss cheese like Andro Rasant Powergrip or BlueFire Turbo series.
Oh yeah and the grip on the Focus 3 sucks, which is why I told you previously anything you get after this rubber you will find amazing the way it lifts backspin or counter loops top spins. Banana flicks will be finally possible.
