Ended up with TW and DD.... I have a DD Frontline which does the job all year round, and a TW basic hammock which is very light. Currently have 4 tarps to choose from
Survival Aids superlight, Issue Basha (heavy but robust) TW Cornelius 3 x 3 great bit of kit, and finally a 3 x 4.5 DD for longer stays
Anyway........my Yorkshire blood refuses to let me part with so much money for anything else
