I don't think going down to 105 was really worth it in the end, you have to drop a lot of height for 15 points.
Looking at my map now. I think I would go
108 116 107 106 112 115 111 120 118 (swap)
102 103 114 110 117 113 119 104 (perhaps miss) 109 101
Yes but dropping one that early is a very big call unless your sure you can not get them all. Without messing up 118 and finding 114 - 110 cleanly I would of been on to clear it just about in time. If your sure you can not get them all then clearly dropping one early is ok but when I think it may be possible I don't want to be too quick to drop one.
