I use all Fermentis yeasts a lot. T-58 is my favorite, and I brew mostly Belgian beers. It has strong clove phenols, but hardly any banana esters. Not really the best for a weizen.
For T-58, picture Leffe Blonde - mostly clove character, a hint of banana. You can skew T-58 more toward clove if you ferment around 60*, but even at higher temps, it won't put off much banana, and it will put off a lot of off-flavors over 70*.
