Equipment preferences

[BlueinLINY]

I'm just starting out my umpiring "career" LOL and was hoping to get some insight and opinions on equipment.

What do you guys prefer in terms of chest protectors (i.e., Wilson Platinum/Gold, Gerry Davis, Honigs, etc.) and shin guards (i.e., double-knee, single-knee). I'm going to have to purchase all my equipment new and was wondering what insight you guys might have since I'm not too familiar with the different types. Which is more comfortable, what can't you live without, etc.?

Thanks for your input, guys.
