Long pips chopper

I am a 1700 rated player and have been using LP OX Dawei 388D-1 for the last 1 year or so. So far my game had been just using an occasional LP by simply returning fast by side swiping on a chop or chop back on a topspin and attack mostly with my FH( Tenergy 05) whenever I was able to create a high ball from the opponent. 

I am beginning to like chopping with my LP and want to convert myself into a modern defending chopper with the ability to attack on FH whenever I get an opportunity. 

1) I am using Stiga Clipper blade and want to know if this setup is too fast for a modern defender? 

2) Also is ox LP the way to go or should I be adding a thin sponge? Is it easier to chop with a sponge or is it easier to chop ox? I have been hearing people using a thin sponge to be able to loop back with LP as well. 

3) Suggestions on how one should correctly chop with LP's. I m struggling to find coaching videos on youtube on LP chopping.

I would recommend staying with your current LP. You know it and know how to use it at the table. It should be fine for chopping. 

In addition to looking for coaching videos of how to chop, I recommend watching match videos with LP-giving you ideas how other players are using them. Also some equipment reviews allow you to look at technique as well. This kid (link below) has a number of them at table tennis experts.

On that note, I personally like the OX pips that have a fairly grippy surface. Curl p4, feint long 3, or the like. I find those are easier to use in the pushing game, whereas with the slicker pips I had a tendency to pop up no-spins or low spun balls. If you don't plan on actually blocking at the table with the pips, then I'd suggest the gripper variety.

Those are not great for blocking, but you can control all types of spin better (aside from very heavy top spin close to the table). You can still use low friction OX, just with a different technique. They require you to hit more into the ball and forward if it's low spin, whereas the grippy ones you can pretty much 'chop' back every ball with an angle/stroke path more similar to inverted.

Yeah, you can learn to handle either of them certainly. I think forehand players don't mind the slicker LPs, since they're mainly just waiting to setup the big kill shot and so their range is usually a bit closer to the table - where the low grip helps in returning . Whereas choppers who really want to chop and win points mainly with that strategy, like the grippier pips since they can do a bit more with them. 

I'm trying to think of a more classic defender I've seen who uses low friction OX LP. Can't name any now... I know of some who use OX but with the high friction pips, and chop all day long. The higher friction pips aren't going to generate a lot of spin by themselves, but it seems to be enough to counter the "just give them dead balls" tactic that attackers spout out. 

So it might be wise to ask yourself - do I plan on waiting to finish with the big forehand, or do I want to win mainly by chopping alone? 

Why don't you step back a couple of feet and try chopping someone's loops in practice with your current setup? My prediction is that it's perfectly fine to chop 1700-2000 level loops, especially after some practice. 

Also, I could be wrong, but chopping away from the table rarely creates opportunities for surprise FH attacks.
