[EX Q]: I have been buying Hi-Tec for years. When I found the Altitude IV I fell in love instantly. This shoe fits great, has little break in time and still holds its sturdiness as it ages. Well recomended.
[EX A]: Positive

[EX Q]: I recall this recording on LP in the early fifties. It conveys the humour and genius of Mozart with great singers although other than Steber they were not previously identified with WM.
[EX A]: Positive

[EX Q]: Return of the Killer Tomatoes is hilarious. Anthony Starke is great. J. Stephen "Rock" Peace is back as Lt. Wilbur Finletter. This is the best movie in the Killer Tomato Triolgy.
[EX A]:
Positive
