Trouble with tires

After getting into a pretty bad accident i replaced the tires i had for a year with performance tires. Vittoria Open Corso 320's. They were fast. I rode my first two organized rides with them, however they fell apart after three months. They were $65 each. I felt like i did not get my money's worth so i went to my repair shop and asked my mechanic what should i get. I wanted something with the following characteristics:

1) Could inflate to a high PSI (over 120). The main reason being my commute path takes me over industrial areas with TONS of potholes. With my original tires i used to get a bunch of pinch flats even fully inflated.

2) Puncture resistant, goes without saying.

3) Low rolling resistance, speed is what i need.

He recommended the Schwable Ultremo ZX. When i got them i was really rooting for them. They looked schmexy on my bike and they felt sticky. However after less than 1 month and immediately after my Nyack ride the rear tire flatted with a serious gash rendering the tire useless. I booted the tire and decided to give the tire a second chance. This past Friday i got the new tire and replaced my back tire. I rode it for the first time on Saturday, a rare chance to ride on Saturday as that's usually the day i have to watch the baby. After 25 miles the rear tire got a serious gash rendering it useless...almost $300 in tires this season...i am about to cry.
