GSB Crampon System

[BVCSK]

As I am in the market for new boots and crampons I have come across this new GSB crampon system which is a collaboration between Grivel and Scarpa.
The system has a metal prong at the toe of the crampon facing backwards and fits into a slot created in the toe of the boot.
I have concerns regarding the slot filling up with various types of debris.
Has anyone got this type of system and what are your comments or does anyone else have other comments or suggestions to make.
The boots I am favouring at the moment are Scarpa Manta's, thoughts and opinions on these too.

Been using manta boots for about 3 years after using berghaus boots for umpteen years. I've found them to be hard-wearing, waterproof (tho' I do re-proof them every 2 or 3 outings), tough and comfy. They are still in great nick considering the mileage they have done and are worn both summer and winter.
I did once take an additional pair of lighter boots with me when I had a longer walk in and out - but that was in the summer when I didn't fancy the idea of stewed tootsies!
Had my money's worth out them and I 'recon they've plenty life left in them yet.
Best thing to do would be to try on a couple of recommended pairs and see what feels most comfortable. I must have tried a half dozen pairs before I decided.

...I must have tried a half dozen pairs before I decided.

I'm getting seriously tired of trying on boots.
Must have tried over 15 pairs now (4 shops in Aviemore, 4 in Inverness) without anything that's said "buy me".

Hello, I had a pair of the new manta and grivel crampons for Xmas and got to wear them the week before last in the Lakes,(see walks outside Scotland-surprise day out-for pics),my husband has the same worries. I left the pegs in because even when we pushed them in they were easy to get out, on the mountain because the rubber became stiffer they were a lot harder to remove. My husband contacted Scarpa who say just leave them out as they were designed to be worn without, although they did send some extra pegs. As to the use they are very quick and easy to put on and think they would take some beating, there is no way they can come adrift,Sue

Just back from a week in Scotland, I was using the new Manta boot across a wide range of terrain and found them to be absolutely excellent in all respects, and very comfortable. I had the Airtech Newmatic crampon but not the GSB version since I didn't want to risk the slot getting full of ice/mud/stones during the walk-in and having to fiddle with getting the crampons on in that situation. It also seems to me that the single front attachment point with the GSB may allow the crampon to twist a bit under the toes; that wouldn't be the case with the 2 attachment point setup at the toe of the non-GSB version.
