Salsa Poco vs. Short-n-Shallow

[divingbiker]

I found my Shimano shortreach levers on eBay.

So do the shortreach levers alone do the trick, or do you need special hoods too? I've already got shims in my levers, and I've got new Salsa Poco bars, but I still can't reach the brakes comfortably. Are shortreach levers what I need? Can you just swap them out without undoing handlebar tape etc?

I have no clue about this stuff...
