Layout and ball advice for thumbless bowler needed

Hey,

a clubmate of us plays thumbless and twohanded (RH) with strikeballs, but uses his thumb on his spareball. :roll:

His acual strikeballs do have a BH at position of thumb ( 1" diameter, 3"deep ) so i took his PAP coordinates like on a onehanded bowler from Gripcenter ( 5 over and 1 5/8 down )

I also took it from middle of bridge fingerholes bottomline ( 5 3/4 over and 2 1/4 down )

Now he asks for new balls and i determined his following specs:

Speed (off hand) : 16,1 mph
RPM: 250
Tilt: 17°
AR: 50°

... specs look like a matched average onehanded bowler for me .

May these layouts be correct and useful for him especially according to the new rules ( no BH ) ?

Anglesum 95°
Ratio: 1,25 :1

Benchmark 55x40
Control 65x50
Long & Strong 75x40
Midlane 50x25
totally strong 45x30

What two new balls and layout combination could be helpful ( 1 for medium condition, 1 for heavy condition )

Something like Jackal ghost (3000 ) or rising ( 2000 ) with benchmark layout for medium-heavy cond?

also a Hypercell fused with control layout for medium cond ?

Does he is classified as a thumbless bowler even when using thumb on spares ? If not, a fake-like thumbhole would be wonderful for increasing ball motion.

Thanks for advice !

yes. not much i know. 5 revs in 1,2 sec makes 10 in 2,4 = 250 rpm
.....his footwork and swing is poor but thats the way he wants to play. He is 50 now and wont change major things.
