TICA shows focus 65% on Head and Body attributes whereas CFA shows focus more on markings, esp. rosettes as you can see in their recent winners. So if you are more confident on his markings, you might wish to consider going for CFA. Many TICA Bengals won shows even with less obvious rosettes or even single-spots but with an incredible head profile. TICA's latest Bengal kitten of the Year is completely single-spotted with normal contrasts but its head profile is unreal:

Their past winners like the one from Jungletrax can attest to this subtle revelation.
CFA show breed standards:

Unfortunately (or fortunately perhaps? lol) there are no TICA shows but only CFA cat shows in my country as my Xander boy will be taking part in the Premier Class championships in Sep 29 2018. So I guess I have to count more on his markings to hopefully get some good placings, LOL.

Recent CFA regional winners with mind-boggling markings:

Hence the current trend seems to indicate that Bengal cats bred with incredible markings but less-than stellar head profile is moving towards CFA shows to get higher placings and recognition (with all basic temperamental factors being equal)
