Long Pips defending rubber

I would surely choose something from TSP,Butterfly or Spinlord.
More from TSP/Butterfly,since SPinlord produces more of defensive shortpips.
For chopping especially Feint rubbers from BTY or TSP Curl series.

it depends on your playing style.

if you like to play at medium distance and have average control, then you can use feint long 2. this rubber doesn't need too much active stroke. you can do almost everything with this rubber with proper technique.

if you like to make heavy backspin with heavy active stroke from long distance, from end point, feint long 3 would suits you. but it will works with really topspin will come to you. and attacking with this rubber is almost impossible.

if you are a master level chopper, curl p1r is the best choice for you. it also can do everything with proper stroke. specially bit higher short pushed ball flat hitting with this is unreturnable. but this would suit you, if you are really a master level chopper, I repeat! as, it is too much sensative with incoming spin.

joola octopus can be said a clone of curl p1r. but it has bit harder pimples and bit more sticky than p1r.

if you like to chop close to the table, curl ph would suits you, I think.

if you like consistancy, you can use grass. but, it is rarely available now a days.

if you like to use a fast long pips, to put every ball at 3rd court of opponent, you can use grass dtecs. it is the fastest longpips for defense. you can also do everything with this, even hitting better than p1r.

if you want bit softer sponge then you can try feint soft (almost unavailable everywhere), it is like feint long 2 with softer sponge; or you can also use speedy soft grass dtecs.

if you like to use chineese rubber, you can try c8, I don't know too much about its property.

if you want to try cheapest rubber, try spinlord products, don't know about specific rubbers.
