Hiya,
I have recently been reading over most of the Kekkei Genkai topics. I found that quite a few Secret Justus like Aburame's Bug Justu and Inzuka's Hidden Justu are wanted by players. May i suggest that a link be added to The Secret Cave saying Hidden Ninjustu Technique's If you select a hidden art it would take away 80dks rather than a complete reset. The reason for losing 80dks would be something along these lines;
You have just finished Hidden Ninjustu Art Aburame, you feel you have mastered the Arts shown to you, although you feel you can improve. As you walk back to your Hidden Village you realise all the time you spent learning the Aburame's Justus you have changed the way you look upon the Shinobi World. As a result you lose 80dks.
This Technique would be a stronger specialty you can choose.
What do you all think, of course this is not perfect, though this idea popped into my head and i went along with it.
