The other thing to remember is the ep's may have life in another scope one day. Your speed (F ratio) and telescope design may change over time.
That is the other advantage of TV's, they will always be able to go to your next scope.
******************
EPs that work well in your current F4.9 will work very well in slower scopes. Fast scopes and wide fields are a good way to hit the wallet real hard.
Look for a list of the 25 brightest/predominate objects in the southern hemisphere - re: nebulosity. Add your scope to something like astronomy tools and look at each object to see what FOV you want. Some are just too big, most you may not need 2degree FOV for either.
