Hi guys!

I'm just curious is there any big difference between cowhide and horsehide for stropping purposes?
I have a possibility to get a cowhide piece and make a belt from it, but don't have any horsehide ATM, and I want to finally start shaving with my straight razor So should I wait and get a horsehide leather or will the cowhide do the job?
Also, does any of them require any additional improvements to be done on them (softening maybe, etc)?

Thanks for your responses.
