Hi Xavier!
i was following some of your posts, and i think we are at a similar level. for me, it was rather easy to learn the basics with a chonkakegoma, so i think it will be easy for you too. though i can play a diabolo too, which helped me more for the chonkakegoma than it did for normal tops ... not sure for the type, i only got a wodden one. since it might be some postage anyway, why not get one wodden and one delrin?
Cheers,
Christoph
