If you would like that 77 str into 80, you cant do it with a whip. I suggest a saradomin sword (ss), or if you dont have the money, a d scimmy/d defender combo. In the event you not or cant however do the monkey insanity pursuit, then I suggest either a brac blade, or OSRS gold even a long if your very low on the moneys.
Additionally, what exactly are you really going to be using this armour for? If coaching without taking much harm (pest control) the I dont suggest using barrows. You should consider getting a fighter chest for coaching since it includes 4 str. It takes some time to get but its well worth it, and the mini game is fun. If you're likely to be slaying or participant fighting in safety (castle wars, duels) then suggest the armour above. You wouldnt imagine how much people will do for an additional 4 str (22 mil for tassy with two str). Paying 4 mil for a ring with 4 str is worth it.
Why Is Everything Crashing? Whips are going down, furys are crashing along with the dfs. Those are just a few ive noticed in the last few days. Other items appear to be moving down at a much faster rate than normal today. The bgs is crashing like a mo fo too. Even sharks are moving down pretty fast, so I dont think its just permanent items. What do you think? Why costs vary, in this case .
People now go pking using fury-s and dfs-s, they drop as loot and people sell themwhen there is more things than demands the cost will drop. Not all is dropping, look at the clue scroll rewards, most of these rised pretty high then it had been earlier. Some dropped, eg. Expensive items begin crashing because players market them to Buy RS gold. This happened following the New Old Wildy was released.
