I have an assortment of pegs I choose each trip based on conditions. If I am going to be in exposed conditions for my overnights, on the tops and expecting high wind/rain, I will take MSR large Groundhogs. If summer, bush conditions, titanium shepards hooks.
MSR now do the groundhogs in mini style. This allows better options at lighter weights.
I just purchase the mini Groundhogs and feel they will work well with all situations if "mixed and matched".
For my Hexamid Zpacks Solo or Twin Tarp, I will now be taking a standard set up of 6 mini Groundhogs and 2 large. The total peg weigh is 90g including the cuben fibre storage sack.
I've included a photo below - the mini groundhogs are on the left with a matchbox to give size comparison. I use the two large one for the front and rear anchor points of my Hexamid Tarp.
These pegs are $4.79 each and available from Outdoor Action - a NZ online store
