Hi craghopper, first of all I’d like to congratulate you on completing this scramble up Jacks rake for the first time. Graded as 1, it would suggest that this scramble could be scaled by any confident hill walker, I did it myself for the first time last year and found it quite a challenge in places and I have done loads of scrambling in North Wales. There are one or two tricky manoeuvres to negotiate on the Rake, especially near to top and there’s also quite a bit of exposure too, which in itself is a challenge, especially for those that suffer from the "big drops syndrome". I see you had a partner with you for the day, IMO that is always a wise choice whenever there is any scrambling involved along your route. Thanks for going to all the trouble of posting your trip report/pictures, I'm sure sharing your experiences with the forum will be of great value to many that haven't taken this scramble on yet.
