I am looking to buy a set of sexing probes soon and wanted to know where you all suggest I get them. I am going to call a few local vets and see if they have a spare set to sell to avoid shipping. Prices are pretty consistent on all of the major sites online, but they sell various sets. Which would you all suggest for everything from baby colubrids to "big" boas. Also, is ball tip definitely the way to go? Also, if anyone knows recommended probe sizes to use with varying ages/sizes of bp's that would be really really helpful.

Thanks,
Austin
