Mentor, advisor , pro or expert or else?

I am working on few membership based websites for diffrent topics, what is better suffix in the domain name: mentor, advisor, pro, expert or something else?
for example : speedreadingadvisor.com or speedreadingpro, or speedreadingmentor .....I already have the speedreadingadvisor.com but for other topics what you think sounds better?

thank you

 

I'd go for advisor -- you already have one and it's not too showy / boastful like expert or pro is.

 

Personally, I would think pro would be the best. Easier for most people to spell, for one thing. It's also shorter and I would think easier to remember.

Just my opinion of course.

Best wishes.

 

I'd go with pro. Nice & short.
