Is Feint Long OX Legal ?

If so, how come Feint OX is certified separately but Feint Long II and Feint Long III are not certified separately ?

 Which ITTF document says this officially ?

I know of scores of USATT tournaments (& heard of in other countries also) over the years where pips players were targetted.

Most umpires are secretly biased more against pips than about smooth rubber players who speed-glue or booster.  

I know of an International  Referee in east coast USA who did not allow OX long pips about 25 years ago. . I do not know if she or he changed now.  I know thre are at least few umpires or even referees who think OX rubbers that are not listed explicitly on ITTF LARC are not legal.

How many tournaments you know of where a player stopped a match in the middle & asked for checking the rackest for speed-glues or boosters ? However I know of scores of cases in USATT tournaments (most of them 2 star or less not some 5 star such as at WVC 2018 where this happened to a Canadian high level chopper ) where a player stopped the match & asked to see the opponents'  pips racket & then asked for a referee to verify that the pips are legal. 

As long as the smooth rubber player is winning , there is no problem even if the pips player is using long pips or anti not listed on LARC.  But as soon as the pips player starts winning it becomes  a huge problem all of a sudden and referee is summoned at least to delay the match & break the pips player's rhythm. I understand most smooth rubber players do NOT do this even if they hate pips but there definitely is a small number of smooth rubber players who do this purposely. 

   In USATT (and I think in most countries)  , to move up from level to level (such as from local umpire to regional umpire), there is a practical portion of the test (in addition to a written test) where you need to umpire under at least a national umpire or above. The national umpire evaluates you & sends a report to USATT. I think you have to umpire a certain number of matches like this under national umpire's supervision.  So do you think you will get a positive review from your examiner (national umpire or above), if you do not examine the rackets of players at all ?
