Exactly, avoid sellecting 1st gear at all if your still moving i'd say!
Probably women who drive Honda Civic's & Toyota Corolla's bang it in 1st gear at any speeds, to a degree on those the gearbox's will cope but eventually premature wear will start to show up, your asking a lot of the gearbox to do that.
Since i bought mine just sometimes it'll crunch a bit on selecting 1st, that's at a complete standstill but i've never forced it, never upon never' brutalised the gearbox and the problem hasn't worsened in the slightest.
Same as a Mk2 i had with the 2nd gear syncro problem, it never got worse because i never used it harshly.
